----------------------------------
Resolution: Fixed
Fix Version/s: 2.4
Synchronized all use of collections in WS-RM acknowledgement processing
(revision 1072914).
> WS-RM ConcurrentModificationException from unsynchronized use of
> SequenceAcknowledgement
> ----------------------------------------------------------------------------------------

> Key: CXF-3273
> URL: https://issues.apache.org/jira/browse/CXF-3273
> Project: CXF
> Issue Type: Bug
> Components: WS-* Components
> Affects Versions: 2.3.2
> Reporter: Dennis Sosnoski
> Fix For: 2.4
>
>
> The WS-RM code needs to use synchronized blocks for both modifying and
> accessing SequenceAcknowledgement. Currently the code appears to use
> synchronized blocks for modifying SequenceAcknowledgement information, but
> not for reading it (for example in RMSoapInterceptor.encode(SoapMessage,
> RMProperties), where the SequenceAcknowledgement is serialized to XML). This
> can result in ConcurrentModificationException:
